[Note Guidelines] Photographer's Note
Far from the water, they aren’t disturbed by sexually active males. They spend their time eating small insects waiting until they are adults, which are sexually active themselves. During this period, their colours (which are very pale after emergence) become brighter. When adult, odonates return to the water to find a partner.
Adult males occupy territories near the water. These territories are defended against other males. When a female of the same species enters the territory, the male grabs her with his appendages: behind or between the eyes (Anisoptera) or at the prothorax (Zygoptera). Two odonates being attached to each other this way are called a tandem. The male transfers his sperm from the opening underneath segment 9 to the copulation device underneath segment 2 by making a loop of his (very flexible) abdomen. Then the female reaches to this copulation device with her genitalia, located underneath her segments 8 and 9. Now the odonates form a loop, called copula or mating wheel. During the copulation, males of some species remove the sperm of earlier copulations (=other males) from the female’s genitalia.
After the copulation, the females start ovipositing. All Zygoptera, most Sympetrum species and Anax parthenope remain in tandem during ovipositing. The other Anisoptera divide after copulation. With many of these species, males guard the females during ovipositing, hovering above them or sitting near them on a plant or stone.

Many Zygoptera (which are endofytic) stick their eggs in the stalks of aquatic plants. Tandems of these species descend on the plant. Then the female walks down backwards, often completely disappearing under the water’s surface. The males, still attached to the females, can pull them out again if they cannot do that themselves, so the males are some kind of lifelines. The abdomen of the female zygoptera are covered with small hairs, between which air is trapped. This air helps them to return to the water surface. Avoid touching the abdomen, for the hairs might break and then the damselflies might never get out of the water again and drown!

I decedit to send this one in from a tandem. Yesterday I saw many of them, I made some good shots but is was to windy to make a very good composition, therefore I send this one, made with my 7000. I hope you like it too.

Hi Jaap,
Excellent pose - I had difficulty deciding which bit belonged to who, but it seems like the only way to travel, and a very complicated way to make love! Typically well composed and very well captured. The colours are lovely and, as ever, the detail is clear and sharp. TFS this wonderful macro. Regards, Vicky

It's taken me a while to sort this puzzle out!
A fantastic image, amazing colours.
Well captured and thanks for posting.

Nice capture Jaap, good to get these into the DOF. Nice composition here and good details. You did very well to capture this moment. Very well done.

Hi Jaap,
Kind of situation I've only seen in photos up to now. Perhaps they are not ready here yet :-). Despite the limitations of a compact, it's a very good composition, very well composed.

Brilliant composition. Great details and beautiful turquoise colours and BG.

Good capture inspite of the windy day you had to work with.Only her wings have blown slightly out of the focus point.
They are a pair of Blue tailed Damselflies (Ischnura elegans) she is I think the colour variation know as rufscens-obsoleta which isthe mature variation of a female that starts off with a blue tail area simular to the male.
TFS them ours are not mature enough yet for this, too cold and windy.

Great capture Jaap,
Excellent detail, colours and sharpness. Great DOF and timing to get this.
Thanks for posting

Nice macro, Jaap.
You catch the tandem very well. Well composed, good PoV and nice colours.
Well done, my friend.

The focus is a little soft but who cares, you've captured and described a unique moment. Thanks for sharing, very enjoyable post.

Hi Jaap
Baie goeie vangs - altwee van julle. his is one that is stil on my wishlist to get. EK het die ysvogeltjie, soos julle noem nie net vir Gert gepos nie, baie het hom geniet. Sodra ek die tyd kry, pos ek 'n tiger dragonfly vir jou. Ons noem hulle naadekokers!
Groetnis

Ha Jaap,

Ik kwam deze in je verzameling tegen. Harstikke goed.
Nu snap ik hoe het werkt bij libelles.
Zelf had ik er ook een gemaakt maar begreep niet waarom de ene de andere in z'n nekvel pakte. (Helaas is mijn camera te beperkt voor betere macro's)
Kijk hier: pole dance
Gisteren zag ik een andere foto bvijna het zelfde hier: The copulation wheel

Bedankt, Hendrik.
